name: wai-sink-swift native sink package

# The native sink's Swift package (wai/wai-sink-swift, extensions/native-sink.md): on the macOS
# runner, the host with the platform SDKs and simulators, libwai is built for every slice of the
# package's binary target (desktop, phone, phone simulator, television, television simulator) and
# the package's tests run on the desktop, and in fresh phone and television simulators hosted in
# TestHost (a device runs no tool-hosted test bundle), every step bounded: the corpus
# live-conformance/native-sink through the Swift wrapper and the C interface; the loopback relay
# over the reference package's floor, presenting what verifies byte for byte and answering 502
# for a fragment changed at the origin; and the platform's player end to end, over a presentation
# made at run time with the platform's own encoder, played through the relay to its end, a changed
# fragment withheld, and a session nobody can see ended as hidden. The phone and television device
# slices are built and linked, not run. Nothing listens beyond loopback.
#
# Push filters match the push's delta, so every path the jobs read is listed.
